The correct answer is: b) Badaga and Saurashtra
Badaga and Saurashtra are two of the many Dravidian languages spoken in Tamil Nadu. Dravidian languages are a family of languages spoken in South Asia, and they are the native languages of the Dravidian peoples. Tamil is the most widely spoken Dravidian language, and it is the official language of Tamil Nadu. Badaga and Saurashtra are two of the many minority languages spoken in Tamil Nadu.
Badaga is a Dravidian language spoken by the Badaga people of the Nilgiri Hills in Tamil Nadu and Kerala. It is a member of the South Dravidian subgroup of the Dravidian language family. Badaga is not mutually intelligible with Tamil or any other Dravidian language.
Saurashtra is a Dravidian language spoken by the Saurashtra people of Tamil Nadu and Kerala. It is a member of the North Dravidian subgroup of the Dravidian language family. Saurashtra is not mutually intelligible with Tamil or any other Dravidian language.
The other options are incorrect because they are not Dravidian languages. Malayalam and Telugu are two of the four major Dravidian languages, along with Tamil and Kannada. Kannada and Tulu are two of the many minor Dravidian languages. Urdu and Marathi are two of the many Indo-Aryan languages spoken in India.
